I grew up in NW Houston JV area and in the mid 90's all we had to get our hands on was sold for 50 a oz. I know now that it is "Mexican Dirt Weed" but back then it was all we had. It sure as hell fucked us up, only after we picked out the countless stems and seeds. It was ugly weed but it did its job and at the time we didn't know better so what the fuck.

Then we discovered better quality weed, it was called dro. Dro was anything that was not Mexican Dirt Weed. Although not really all grown in Hydro (we did not know that then) it was sold for 10-20/gr depending on the source and quality.

So there was two kinds:
Mexican Dirt Weed or
'Dro


Then I moved to Olympia, Wa.
In Olympia there is:

Shwag = 25 for an 1/8 (usually has seeds)
Reg's = 40 for an 1/8 (weighed at 4.0 grams) maybe a couple seeds
Fire = 45-60 for an 1/8th (weighed at 3.5 grams) NO SEEDS. looks like weed in a magazine photo.

BUT NO MEXICAN DIRT WEED..

I have seen seeded cannabis but no pressed brick weed (THANK GOD)

of course this is all relative to my experience and exposure to smokers, buyers and people which has been immense.
